Tight facial mask and preparation method thereof

Abstract

The invention relates to a tight facial mask, which comprises a facial mask body, a tape group, a pair of upper connecting marks and a pair of lower connecting marks, wherein the facial mask body comprises an upper main body and a lower main body part; the lower main body part is overlapped on the upper main body part, so that a sealing edge is distinguished between the upper main body par and the lower main body part; the tape group is composed of a plurality of tape bodies which are fixedly connected on two sides of the facial mask body; the pair of upper connecting marks are formed on the left and right sides of the upper main body part; the pair of lower connecting marks are formed on the left and right sides of the lower main body part; and the pair of upper connecting marks, corresponding to the pair of lower connecting marks, are directly or indirectly connected to and extend to the sealing edge, so that two sides or partial two sides of the facial mask body are sealed. Therefore, an average density value is measured to be 32-45, and an average upgrade rate is improved by 10-15 times.

Description

technical field [0001] The invention relates to a mask, in particular to a tight-fitting mask and a method for making the same. Background technique [0002] With the serious air pollution, the concentration of suspended particles, sand, dust or vehicle exhaust in the air is inhaled into the lungs through the mouth and nose of the human body, and long-term accumulation causes damage to organs, cells or mucous membranes, resulting in chronic diseases and diseases, which are harmful to human health. huge influence. [0003] According to the research report, due to factors such as improper size of the mask, excessive wearing time, or incorrect use of the commonly used flat masks, the fit between the wearer's face and the mask will be affected, resulting in poor fit and air leakage. , thereby affecting the protective effect. Therefore, an appropriate mask body, which makes the wearer feel comfortable and meets the requirements of tightness, is a key and important factor. [0...

AI Technical Summary

Problems solved by technology

[0004] Generally, the flat non-woven masks on the market, due to the low tightness, most of the air leaks through the pores between the mask and the cheeks, and the tightness is tested by the TSI8038 mask tightness tester, and the test results show the average tightness value It is only 3.1. However, in the development process of the above-mentioned flat non-woven masks, the average closeness value can only be increased to 5 to 6 after decades of research (the average increase
